ductors and particularly to that class of support known as conductor clamp by means of which a trolley wire or other conductor may be gripped and supported from a suport.

The object of my invention is to produce a simple, cheap and eflicient device and my invention resides in the new and novel construction, combination and relatlon of the various parts hereinafter more fully described, and shown in the accompanying drawings.

A In the drawings i j .Fig. lis aside view in elevation of a support embodying my inventlonand shown as 26 gripping'a trolley wire, and also shown as vsecured to a hanger H r Fig. 2 is an end view inpartial section of the device shown in Fig. 1. r

Fig. 3 is an end View in partial section of mydevice shown with the jaws open in position ready to receive the conductor.

Fig. 4 is a longitudinal view on the line 1----4ofliig. 3. I Fig. 5 is a sectional view on the line 5- 5 In the preferred form of device embodying :my invention I employ a supporting member lprovided at the upper end with a flange 2 and with a threaded recess 3 to rea0 ceive the threaded stud of the hanger H.

The lower end of the member 1 is provided with oppositely and symmetrically disposed grooves 4 extending in a longitudinal direction with respect to the clamp or conducton 5. y

Rotatably mounted upon the support 1 is an operating member 6 provided with polygonal faces 7 to receive a wrench. The member 6 is provided with an internally threaded recess 8 engagingwiththe thread 9 on the member '1. By rotating the member 6 it. will move toward or away from the flange 2 due, to its threaded engagement with the member 1. i

Slidably, but non-rotatably, mounted upon the member'l is an intermediate member 10 having a facell to engage with the face 12 of the operating member 6. The member 10 is provided with two longitudinally dis-.

posed semi-circular channels 13 positioned on opposite sides of the center line to receive in pivotal engagement therewiththe clamping members 14. The channels 13 may beof. other shapes than shown without effecting the operation of the device. Projecting downwardly and adjacent the channels are lugs 15 which are originally formed straight as shown by the dotted line, and after-the jaws 14 are positioned in place are bent over thereby locking the jaws in position, butin pivotal relation with the intermediate mem-* her 10. H

The jaws 14 are each provided with alongitudinally disposed member 16 shaped to conform to the curvature of the channel 13.

The loweredge of eachjaw is provided with lip'17 to engage the groove 18 of the conductor 5. The jaws are each provided with'a flange 19 which is positioned in the groove a.

4. The member 20 forming the lower face of the groove 4; acts as asupport forthe flanges 19 which slide and pivot upon the member 20 as the jaws 14 aremoved into or out of engagement with the conductor 5'; It wwill be plainly seen that if the member 10.

and of necessity the jaws, are moved relative to the supporting member 1 thatthe' jaws will be movedinto or out ofengagement with the conductor 5. Secured to the upper edge of the member 6 is a flange 21 which originally was formed straight, but which I after assembly of the parts is turned inwardly by any well known means so that it will engage with the flange 2 thereby limiting the upward movement of the member 6 relative to the member 1 andipreventingthe dis-assembly of the parts.

The passage through the member 10 is provided with two oppositely disposed slots 22 and the member 1 is provided wlth oppo:

sitely disposed ribs 23 each engaging in one of the slots 22 to prevent relative rotation of the member 10 with respect to the member 1.

In'the use of my device, the same is first installed upon the, stud ofthe hanger H by means of the threaded recess 3. The: jaws are then brought into alinement with the conductor 1 which is raised up into position between. the lips 17 and the member 6 is then rotated in a direction which will" move it downwardly relative to the member 1 and into engagement with the member 10 which in turn will move the, jaws downwardly, but on account of their engagement with the member 1 due to. the flange 19. interengaging with the slot/l], the lips-l7 of the jaws will be'inoved inwardly simultaneous with the downward movement of the jaws until the liPS. engage'the conductor 5,. By applying a wrench to, the, polygonal faces 7 the jaws can be brought into firm and secure engage.-

mentwith the conductor 5. j

It will, be observed that the jaws 1,4: are pivotally secured to the member 10 and whenthe device is operated to move the jaws into engagement with. the conductor 5 thatthe, jawsfpiv ot in its channel 13 and the flanges 19 of, the jaws have a sliding and pivotal relation relative to the member 20.

There are, of course, many modifications ozE my. invention which may be made and will be apparent to those skilled in the, art, but I do not wishjto be limited other than by my claims. i
